PREFACE.
(FIRST EDITION.) Professor Peterson, in his Fifth Report on the Search for Sanskrit Manuscripts in the Bombay Circle, mentions a Jaina Sanskrit work called Nyāyāvatāra by Siddha Sena Divākara. A manuscript of this work, together with a commentary on it called Nyāyāvatāra-vivrti, was kindly procured for me from a private library in Bhavanagara, Bombay, by the well-known Svetāmbara Sadhus, Sastravisarada Jainacharyya Vijaya Dharma Suri and Upadhyaya Indravijaya.
Seeing that the Nyāyāvatāra is a very important work, being the earliest known Jaina treatise on Pure Logic, I have, in the present volume, attached the text of it with extracts from its verbose commentary. I have also included in the volume an English translation which I prepared for the “Journal” of the Indian Research Society of Calcutta. The notes which I have added to elucidate the translation are based on the commentary already referred to.
I acknowledge with thanks that Mr. C. Russell, M.A., Principal, Patna College, has kindly helped me with a number of suggestions while the translation was passing through the press.
